I started a thread on this about a month ago (was too lazy to find it, so started a new one.) Anyways, when i play games with my 8600 gts 512mb graphics card, after about 5-10 mins of gameplay i experience weird colorful lines across my moniter (i think this is called artifacting.) I was told that my card was overheating because i didn't have enough amps to power my card. So, i bought an ULTRA 600 watt ATX power supply with 35 amps on the 12 v rail. When i play games... i get the same problem. Can anyone help?
